OBJECTIVE 2: TO IMPROVE AND PROMOTE SAFETY AND HEALTH INNOVATION IN THE SECTOR
OBJECTIVE 2 - PROGRESS REPORT 3x CSPAC Innovation in Safety Awards: 1. ‘Innovation in Safety - Design’ - 2018 Winner: Ward & Burke Construction Limited 2. ‘Innovation in Safety - Construction & Maintenance’ - 2018 Winner: BAM Building 3. ‘Innovation in Safety - Products and Services’ - 2018 Winner: Salus Training Services Limited
INNOVATION IN SAFETY – CONSTRUCTION & MAINTENANCE 2018 Winner : BAM Building • The BAM Ireland project team on the Blackpitts Hotel and Blackpitts Student Accommodation projects undertook a pilot study to look at how the risk of workers being exposed to RCS dust could be eliminated as far as possible: – Using Building Information Modelling (BIM) to design out the hazard – Co-operation with designers at an early stage to allow for using products that eliminated the production of RCS dust – Partnership approach with Hilti, tool supplier, where 95% of sub-contractors purchased extraction units for their tools – Maintaining awareness, via site induction, RCS dust notice boards and regular talks meant that all contractors were aware of the policies and procedures and the elimination of RCS became the acceptable norm – Regular auditing of compliance – Using full face masks for RPE prevented inhalation of RCS dust, ensured eye protection didn't steam-up and eliminated the need to be close shaven.
INNOVATION IN SAFETY – CONSTRUCTION & MAINTENANCE 2018 Winner : BAM Building
OBJECTIVE 4: OCCUPATIONAL HEALTH IN CONSTRUCTION
OBJECTIVE 4 – PROGRESS REPORT • Continued focus to raise awareness of risks from construction dusts and to promote safer work practices in the industry: – Participation in Social Dialogue Workshops on RCS with FIEC & EFBWW – Information pack on RCS developed for the construction sector • Raise awareness of risks of other occupational related cancers such as the increased risk of skin cancer for outdoor workers • Working group established to develop a mental health and wellbeing support solution for the sector.
MANAGEMENT OF RCS IN CONSTRUCTION
HOW MUCH DO YOU KNOW ABOUT RCS? 1. What is RCS? – Crystalline silica is a naturally occurring substance typically found in stone (particularly sandstone, shale, granite and slate), in sand and also in products such as bricks, tiles, concrete and cement. Respirable Crystalline Silica (RCS) occurs when these materials are worked on to release a very fine, inhalable dust. 2. How can a person be exposed to RCS? – Where concrete, stone or sand based materials are altered (during formation, cutting, drilling, polishing or demolition) and made airborne, there is a potential for exposure to crystalline silica dust. 3. What are the routes of entry for RCS into the body? – Inhalation is the primary route of exposure to crystalline silica dust. – When any dust is inhaled, its point of deposition within the respiratory system is very much dependent upon the range of particle sizes present in the dust. The respirable fraction (smallest particle size) of crystalline silica dust can penetrate deep into the lungs.
HOW MUCH DO YOU KNOW ABOUT RCS? 4. What are the health impacts of exposure to RCS? – Silica dust is only harmful when it is inhaled deep into the lungs. Inhalation of fine dust containing crystalline silica can cause silicosis of the lungs, which in severe cases can be disabling, or even fatal. 5. How can a worker prevent exposure to RCS? – The respirable fraction of the dust is invisibly fine. Elimination and substitution of RCS containing materials, dust extraction and/or dust suppression are the primary measures advised to control potential exposure. 6. What Respiratory Protective Equipment (RPE) provides adequate protection? – Respiratory Protective Equipment (RPE) should either be a FFP3 disposable respirator or a P3 particulate filter fitted to a half or full face mask to provide effective protection and be CE marked. RPE is selected as a control measure when engineering and work practice controls cannot maintain exposures at or below the OELV
INDUSTRY GUIDANCE FOR RCS • Industry Guidance Manual for Addressing Potential Risks from Worker Exposure to Respirable Crystalline Silica (RCS) on Construction Sites: https://cif.ie/safety/ • Approach promoted by industry is to manage all dusts, including but not limited to RCS • Manage dust of differing particle size: – Floating particles < 75 μ m – Fine-grained dust < 5 μ m – Visible dust > 20 μ m
EU GUIDANCE FOR INSPECTORATE https://osha.europa.eu/en/guidance- national-labour-inspectors-on-addressing- risks-from-worker-exposure-to-respirable- crystalline-silica
TOOLS FOR TRAINING & AWARENESS Toolbox Talks developed for key work activities that have the potential to generate dust, including RCS.
OCCUPATIONAL MONITORING FOR RCS • OELV of 0.1mg/m3 (8 hour reference period), as set down in the HSA’ 2018 Code of Practice for the Chemical Agents Regulations • Support for 2x MSc. students investigating exposure to RCS on construction sites
PREVALENCE & DURATION OF DUST • Dust remains airborne based on a number of factors, not least particle size (e.g. concrete dust ~1-100 μ m; human hair: 100 μ m; tobacco smoke ~ 0.1-5 μ m). • Assuming a fall height of 1-metre above ground, it would take the following timeframes for dust to settle: 50 μ m - 10 seconds 10 μ m - 5 minutes 1 μ m - 7 hours 0.1 μ m - more than 12 days Source: Hilti On-Site Dust Solutions 2018

LEANER, CLEANER, SAFER WORK PRACTICES Adopt the Hierarchy of Control Measures: https://www.hsa.ie/eng/Topics/Hazards/ • Avoid dry-sweeping; • Select vacuums equipped with HEPA filtration (type-H); • Prioritise dust extraction / containment mechanisms; • Utilise appropriate dust suppression techniques; • Adhere to collective protection measures.
